This is not what the function is about... that's done by my
pl08x_select_bus() function.
This function (pl08x_choose_master_bus) does something completely
different, and has to do with how the LLIs are laid out. I think
it's to do with whether we use the source or destination for
alignment purposes.
It really has nothing to do with choosing busses.
